the position of the mouse

[branaway]

Can I ask a simple question? How can I find out the world position of the mouth of the VRM model in a scene?

sorry for my slippery finger. I should have been mouth in the title.

Unfortunately, you cannot get the exact position of the mouth of avatars.

However, you can get a position of the head bone (located at the root of the head) instead.
Try having a hardcoded offset (say, (0.0, 0.03, 0.03)) and use Object3D.localToWorld, like this code below (not tested):

const headNode = vrm.humanoid.getNormalizedBoneNode('head');
const offset = new THREE.Vector3(0.0, 0.03, 0.03);
headNode.localToWorld(offset);
